20 cally Patented Dec. 6, 1932 UNITED STATES PATENT OFFICE FRANK A. TALBOT, F BALTIMORE MARYLAND, ASSIGNOR 0F T0 WILLIAM B. W. MANN, 0F BALTIMORE, MARYLAND NONBEFILLABLE RECEIPTACLE Application illed September 25, 1931. Serial No. 565,155.

This invention relates to improvements in receptacles of the type to be used only once, that is, of the kind which cannot be refilled through the same passageway employed in 4t5 the initial filling.

The primary object of the invention is to furnish for this purpose improved liquid and air passageways combined with suitable bafie means and a valve, all so constructed that the device may be manufactured at relatively small ex ense, and which will be practical and dura le in action.

Another object is to provide a receptacle of the non-refillable type, in which the valve which prevents refilling, is initially held off its seat by a suitable retainer; said retainer when the closing plug of the receptacle is inserted, functioning to release the valve retaining means, whereby the valve automatiseats, when the closure plug is attached to t e receptacle.

A further object is to furnish a device of this character,in which the valve may be initially held off its seat by magnetically operated means; such means, when actuated by a magnet, functioning to move out of obstructing position so .that the valve may automatically close.

Astill further object is to provide a de- 50 vice of this kind, having the valve initially held off its seat by distortable pins or the like, which may be distorted by movement of the passageway baille, the latter being actuated either by magnetic or mechanical means.

A further object is to provide such structures with means to facilitate their attachment to the conventional pump used at the top of an oil dispensing drum or the like,

whereby as the liquid is pumped from the d drum or barrel, air may enter the latter through the pump to displace the oil discharged.

With the foregoing objects outlined and with other objects in view which will appear as the description proceeds, the invention consists in the novel features hereinafter described in detail, illustrated in the accompanying drawings, and more particularly pointed out in the appended claims.

In the drawings,

Fig. 1 is a vertical sectional view of one form of the device, as employed in connection with a nonrellable drum.

Fig. 2 is a horizontal sectional view of the same on the line 2-2 of Fig. 1.

Fig. 3 is a vertical sectional vlew of a modilication.

trated in Figs. 1v and 2, 8 designates the shell of the improved structure which may be shaped at its bottom as shown at 9, to be connected to the down pipe 10 which extends from the top to thebottom of an oil drum. In forming the shell from sheet metal, it is preferably provided with an annular trou h, as shown at 11, for a purpose hereinafter escribed. v

The upper end of the shell is crimped, as shown at 12, to an annular ledge 13 which is positioned below the extreme upper surface 14.-'of the top ring 15 of the device, so that channels or grooves 16 radially placed in sald upper surface will function to admit air to the drum beneath the head 17 of the latter, while oil is being withdrawn from the rum.

In accordance with the invention,'the top part of the rin 15, as best shown in Fig. 7 is preferabl o octagonal shape, as indicated at 18, and t is specially shaped aperture has its wall undercut or recessed as at 19 in Fig. 1. This permits the sheet metal forming thehead of the drum to be crimped about our sides of the octagonal wall and into the recess, but on the other four alternate sides of such wall, where the channels or grooves 16 are placed, the metal can be left uncrimped, so

An inverted annular channel or trough is positioned in the under side of the top ring 15, and asbest shown in Fig. 3, upwardly eirtending arms 21 of a cup-shaped baille 22 extend into the upper channel while legs 23v ofthe same baille project into the trough 11. This arrangement enables the baille to be rigidly secured to the shell and top' rin'g, as will be the case in the construction shown in Figs. 1, 2 andv3, or to rotate within the Figs. 4, 5 'and 6.

20 valve employed to close the lower end of the shell, as will be explainedin connection with In each form of the-invention there isa shell to prevent refilling of the receptacle, but

the valve in the beginning is retained in open position so that the vessel may be filled through the top ring 15, and the inilowing liquid will flow between the arms 21 of the baille, then through 'the annular space'24 between the baille and shell, and thence between the legs 23, and finally through the bottom opening ofthe shell.

` This valve is designated 25 in Fig. 1, 25a

in Fig. 3, and 25o in-Fi s. 4, 5 and 6.

The means for initial y retaining the valve in openposition in Figs. 1 and 2 consist of a resilient metal yoke or inverted U-shaped member 26 which extends dialnetrically across the cup forming the baille, and has hook legs 27 which extend beneath the valve 25 so as to normally prevent a spring 28 from forcing the valve on to its seat 29.

The closing plug 30 for the drum, is employed yto actuate this valve retainer, and it will be observed that for this purpose,the threadedskirt 31 is slightly longer than usual, whereby when the plug 1s screwed into the threaded portion 32 of the top ring, its skirt will move the diametrical ortion of the retainer downwardly as in icated in dotted l1nes, whereby the hook legs -will be removed from beneath the valve and `the spring 28 will force the latter to its seat.

From this it will be understood that while the receptacle is being initially filled, the retainer 26 will prevent the valve from closing, but when the sealing plug 30 is attached, 1t will function to move the retainer so that the latter will release the valve and thehvalve.

will seat. From thattime on, the spring 28 connection with the plug 30 to close any exit` from the air grooves 16 to prevent any outportion 32 of the top ring.

ward seepage-of oil through these 'grooves while the receptacle is in transit.

If preferred, as sho-wn in Fig. 3, the valve 25a may be initially held oil its seat by a bow spring 26a which is positioned beneath the valve and has legsv 27u/l resting on the lower portion ,of the shell. -In` this ease, the

valve will be spaced slightly from the bottom 22a of the baille, and will be formed ot magnetic material, and when magnetieforce is exertedA upwardlyA through the opening .1n the top of the device, the valve 25a will r1se slightly and the legs 27a, under their own resiliency, will spring toward one another so that the retainer 26a will drop into the pipe 10a, and then the spring-28a will force the valve to its seat, when the magnetic force is released.

As shown in- Figs. 4 to 6 inclusive, the valve can be initially retained oil' its seat by distortable arms 'or pins 40 which project jinwardly from the wall of the shell and initially support the valve 25o. In this event, the baille 226` will be rotatably arranged within the shell, and consequentl when the baille is rotated about the axis o the shell, its legs 23a will strike the pins and bend the same out of valve obstructing position, as indicated in Fig. 5. Then the spring 285 will act to seat the valve. Y

The baille in this instance can be rotated by any suitable magnetic tool inserted through the top of the device, or the baille may have its .cylindrical wall provided 'with inwardly pressed protrusions 220 that may .be

engaged by any special turning tool built for.

the purpose.

As illustrated in Fig. 6, any of the forms ico of the device described may be employedin connection with a conventional suction pump provided the latter is equipped with an iinproved adapter. As illustrated in this figure, a onventional pump 50V has a suction pipe 51, and this pipe is provided at its lower end with a nut 52 that is externally threaded so that it may be screwed yint-o the threaded threaded collar 53 is secured to the base portion of the pump and'bears on the sealingv gasket 33, after the sealing plug is removed. With this arrangement, the external passageway 54 of the pump communicates by' way of the grooves 16 shown in Fig. 7 with the interior of the receptacle, so that air may flow through the'pump into the 'receptacle while oil isv withdrawn from the latter through the pipe 10 and past theA valfe 250.

' In all of my constructions, as th'e valve 25, 25a, 25o is supported by the shell orcup 8 secured to the top `17 of the drum, the down pipe 10, 10a may be made of a thin tin tube which .may be of inexpensive and light construction. Furthermore, the arrangement of the valve at the top of the drum eliminates the necessity of employing a suction Another irs iso

valve in the pump, as my valve is arranged suhciently close to the pump to serve asa suction valve for the same. Moreover, as the down tube does not have to carry a valve, and therefore may be made of light material, it is unnecessary to anchor its lower end to the bottom of the drum where 'it extends into the sump, (Fig. 6).

In the last mentioned figure, the construction is also such that the pump may face in any direction relatively to the drum. As advertising matter is usually placed at one side of such a drum, it is desirable that the pump face in that direction. In accordance with my invention, the member 52 can be screwed downwardly to a desired depth within the ring 32, and then the pump may be turned to face the pump in the desired direction. Afterwards, the nut 53 can be screwed down on to the gasket 33 to make a tight joint and to prevent the pump from accidentally moving out of proper position relatively to the advertising matter on the drum. In other words, my parts 51, 52 and 53 are of such construction relatively to the drum, that they in effect form a swivel connection for securing the pump to the drum.

From the foregoing it is believed that the various forms of the invention which have been illustrated may be clearly understood, and it is manifest that changes may be made in the details disclosed, without departing from the spirit of the invention, as expressed in the claims.
